Love handles, essentially (4)
I believe the answer is:
flab
'love handles essentially' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for flab that I've seen before include "spare tyre?" , "Sign of over-indulgence" , "Loose flesh; fat" , "Fat acquired by over-eating" , "Informally, unsightly fat" .)
